Title:
JOINING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/213492
Kind Code:
A1
Abstract:
A second member (20) is formed from a material that is difficult to weld to a first member (10). The first member (10) has formed therein a blind hole (11) having a depth that does not penetrate through in the thickness direction. A third member (30) is welded through a penetrating portion (21) of the second member (20) to an inner circumferential surface and a bottom portion of the blind hole (11), and to an opening surface (10a) of the first member (10) opened by means of the penetration portion (11) of the second member (20). Solidification contraction of the third member (30) causes the second member (20) to be compressed between a flange portion (31) and the first member (10), thereby fixing the second member (20) between the flange portion (31) of the third member (30) and the first member (10).
